Description

多小区物理下行控制信道监测能力的分配方法和装置Method and device for allocating monitoring capability of multi-cell physical downlink control channel

技术领域technical field

本申请实施例涉及通信技术领域。The embodiment of the present application relates to the technical field of communications.

背景技术Background technique

网络设备(例如基站)在物理下行控制信道(PDCCH，Physical Downlink Control Channel)上发送控制命令，用户设备(UE，User Equipment)需要在对应的小区监测PDCCH。用户设备盲检PDCCH的各种可能性构成的集合称为搜索空间，用户设备在信道上盲检PDCCH的时频资源为控制资源集合(coreset，control-resource set)。A network device (such as a base station) sends a control command on a Physical Downlink Control Channel (PDCCH, Physical Downlink Control Channel), and a user equipment (UE, User Equipment) needs to monitor the PDCCH in a corresponding cell. The set composed of various possibilities for user equipment to blindly detect PDCCH is called a search space, and the time-frequency resource for user equipment to blindly detect PDCCH on a channel is called a control resource set (coreset, control-resource set).

用户设备在一个coreset上监测PDCCH由自身能力决定。在一个服务小区的一个时隙(slot)内，通过最大盲检次数(即PDCCH最大监测数目)和非重叠控制信道元素(CCE，Control Channel Element)的最大数目这两个指标来描述PDCCH监测能力。其中，PDCCH的资源粒度是CCE，一个CCE由6个资源元素组(REG，Resource Element Group)组成，一个REG是由连续的12个资源元素(RE，Resource Element)组成。It is determined by the user equipment's own capability to monitor the PDCCH on a coreset. In a time slot (slot) of a serving cell, the PDCCH monitoring capability is described by the two indicators of the maximum number of blind detection times (that is, the maximum number of PDCCH monitoring) and the maximum number of non-overlapping control channel elements (CCE, Control Channel Element) . Among them, the resource granularity of PDCCH is CCE, a CCE is composed of 6 resource element groups (REG, Resource Element Group), and a REG is composed of 12 consecutive resource elements (RE, Resource Element).

最大盲检次数和非重叠CCE的最大数目都是具体到一个小区的一个时间单位(例如时隙slot)计算的，而且它们随着子载波间隔(SCS，Sub-Carrier Spacing)的增大而减小。当一个用户设备有能力监测多个下行服务小区的PDCCH时，其监测能力需要分配给各个小区。Both the maximum number of blind detection times and the maximum number of non-overlapping CCEs are calculated specific to a time unit (such as a time slot slot) of a cell, and they decrease as the sub-carrier spacing (SCS, Sub-Carrier Spacing) increases. Small. When a user equipment is capable of monitoring PDCCHs of multiple downlink serving cells, its monitoring capability needs to be allocated to each cell.

The embodiment of the present application involves a terminal device monitoring PDCCHs of multiple downlink serving cells simultaneously, and each serving cell may have different subcarrier intervals. A terminal device has the ability to monitor PDCCHs on multiple serving cells. This capability corresponds to the number of monitored cells which can be identified as

The terminal equipment allocates monitoring capabilities for each serving cell, and may calculate the PDCCH monitoring capabilities according to the time unit of PDCCH monitoring.

或者盲检PDCCH时不重叠的CCE数目不能超过

When the number of cells configured for terminal equipment to monitor PDCCH exceeds its capacity, that is

, corresponding to the subcarrier spacing μ, span(X,Y), the ability of the terminal device to blindly detect the PDCCH cannot exceed

Or the number of non-overlapping CCEs cannot exceed

以上对于以slot和span计算PDCCH监测能力进行了示意性说明。The above schematically illustrates the calculation of the PDCCH monitoring capability by using slots and spans.

Rel-17正在研究52.6GHz-71GHz(FR 2-2)的波形和信道接入设计。在该频段相位噪声影响非常严重。为了解决这一问题，需要增加子载波间隔来减弱相位噪声的影响。随之而来的问题是在新子载波间隔480KHz(μ＝5)和960KHz(μ＝6)的时候，终端设备能力有限，如果继续按照slot为单位计算PDCCH监测能力，终端设备不能正常工作。Rel-17 is studying the waveform and channel access design for 52.6GHz-71GHz (FR 2-2). The phase noise effect is very serious in this frequency band. In order to solve this problem, it is necessary to increase the subcarrier spacing to reduce the influence of phase noise. The ensuing problem is that when the new subcarrier spacing is 480KHz (μ=5) and 960KHz (μ=6), the capability of the terminal equipment is limited. If the PDCCH monitoring capability is calculated in units of slots, the terminal equipment cannot work normally.

例如在μ＝6时，盲检PDCCH时的每时隙每服务小区非重叠CCE的最大数目有可能小于16，从而导致终端设备不能正常工作。For example, when μ=6, the maximum number of non-overlapping CCEs per time slot and per serving cell during blind detection of PDCCH may be less than 16, thus causing the terminal equipment to fail to work normally.

表1是针对μ∈{0，1，2，3}每时隙监测PDCCH候选的最大数目，表2是针对μ∈{0，1，2，3}每时隙非重叠CCE的最大数目，具体可以参考现有标准文本38.213。Table 1 is the maximum number of monitored PDCCH candidates per slot for μ ∈ {0, 1, 2, 3}, Table 2 is the maximum number of non-overlapping CCEs per slot for μ ∈ {0, 1, 2, 3}, For details, please refer to the existing standard text 38.213.

终端设备不被要求监测多于对应所述子载波间隔的总非重叠控制信道元素数目的非重叠控制信道元素，所述总非重叠控制信道元素数目等于按具有当前子载波间隔的待监测物理下行控制信道的小区数目和所有待监测物理下行控制信道的小区数目之间的比例分配后对应所述子载波间隔的非重叠控制信道元素的数目。The terminal device is not required to monitor more non-overlapping control channel elements than the total number of non-overlapping control channel elements corresponding to the subcarrier spacing, the total number of non-overlapping control channel elements is equal to the physical downlink to be monitored with the current subcarrier spacing The ratio between the number of cells of the control channel and the number of cells of all physical downlink control channels to be monitored corresponds to the number of non-overlapping control channel elements in the subcarrier interval after allocation.

具体地，例如：Specifically, for example:

为子载波间隔μ的总物理下行控制信道候选数目，

为子载波间隔μ的物理下行控制信道候选的最大监测数目；

为子载波间隔μ的总非重叠控制信道元素数目，

is the maximum monitored number of physical downlink control channel candidates with subcarrier spacing μ;

maximum number of non-overlapping control channel elements with subcarrier spacing μ;

is the total number of PDCCH downlink serving cells that the terminal equipment is capable of monitoring with slot and slot-group as the time unit,

is the number of downlink cells configured by the network device, and α ^μ is the proportional coefficient between the time slot group size of the current subcarrier spacing and the time slot size of the reference subcarrier spacing.

时，

和

hour,

and

例如，在上述公式的计算中，多个子载波间隔中从子载波间隔参数μ开始计算，其中μ＝0。即，从0开始计算多小区PDCCH监测能力。For example, in the calculation of the above formula, the calculation starts from the subcarrier spacing parameter μ among multiple subcarrier spacings, where μ=0. That is, the multi-cell PDCCH monitoring capability is calculated starting from 0.

再例如，在上述公式的计算中，多个子载波间隔中从子载波间隔参数μ开始计算，其中μ为大于0小于5的整数。即，μ取值从大于0小于5的某一整数开始，为多小区调度传输计算多小区PDCCH监测能力。此时，集合μ′∈{0,1,...,μ-1}对应的上述公式中，

和

的数值为0。由此，考虑μ的取值范围，能够使子载波间隔跨度减小，从而降低调度负担。 For another example, in the calculation of the above formula, the multiple subcarrier spacings are calculated starting from the subcarrier spacing parameter μ, where μ is an integer greater than 0 and less than 5. That is, the value of μ starts from a certain integer greater than 0 and less than 5, and multi-cell PDCCH monitoring capability is calculated for multi-cell scheduled transmission. At this time, in the above formula corresponding to the set μ′∈{0,1,...,μ-1},
